US researchers develop technology to 3D print cells on skin

Researchers at the University of Minnesota in the US have developed technology capable of directly 3D printing biological cells and electronics on skin in real-time.

The portable, customised 3D printer is expected to aid in developing new medical treatments for wound healing and allow direct printing of grafts to treat skin disorders.

In addition, the low-cost technology could help soldiers if used to create temporary sensors capable of detecting chemical or biological agents. It could also aid in the 3D printing of solar cells that can charge electronics.
